JCE Classroom Activity #28 is an adaption of an acid-base reaction generating carbon dioxide gas that allows blind students to observe the results. Based on the 2000 Pimentel Award Adress, Every Year Begins a Millennium by Jerry A. Bell, this activity is intended to show sighted students that gathering all the information available in the chemistry laboratory will engage all of their senses.
Supplement
Experiment 1, the reaction of sodium bicarbonate (baking soda) with cream of tartar in water, is performed by a blindfolded experimenter in this video.
The video requires QuickTime 4 or higher. QuickTime can be downloaded here.
